Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they are still present but cannot be diagnosed in the current context).

The "present" or "stored" status of faults must be taken into account when using the diagnostic tool after switching on the + after ignition (without activating the system components).

Deal with present faults according to the procedure shown in the section on "Interpretation of faults". For a stored fault, note the faults displayed and follow the instructions shown in the "Notes" section. If the fault is confirmed when the notes are applied, the fault is present. In this case, deal with the fault. If the fault is not confirmed, check:

– the electrical lines which correspond to the fault,

– the connectors on these lines (corrosion, bent pins, etc.), – the resistance of the component detected as faulty,

(6)

Check the battery charge and the condition of the fuses

Print the system fault finding log (available on CLIP and in the

Workshop Repair Manual or Technical Note)

Connect CLIP

(7)

You will always be asked for this sheet:

● When requesting technical assistance from the Techline.

● When requesting approval to replace parts for which approval is compulsory.

● To be attached to "monitored" parts required to be returned. The log is required for warranty reimbursement, and enables better analysis of the parts removed.

IMPORTANT!

NOTE

All faults in a complex system require a thorough diagnostic check with the appropriate tools. The FAULT FINDING LOG, which should be completed during the procedure, enables you to keep track of the fault finding carried out. It is an essential document for consultation with the manufacturer.

IT IS THEREFORE COMPULSORY TO COMPLETE A FAULT FINDING LOG EVERY TIME FAULT FINDING IS CARRIED OUT.

The automatic transmission on this model is the DP0, which is also found on other Renault vehicles including Laguna II, Clio II and Kangoo.

The automatic transmission computer controls gear-changing using several parameters, among them engine torque and the driver's driving style.

All signals travel to the computer by wire, except for those from the injection computer, which use the multiplex network.

Line K is used for computer diagnostics.

If Techline approves the computer replacement, proceed as follows:

– In the "Identification" menu, find the gearbox oil wear meter code. – Switch off the ignition.

– Replace the computer.

– If necessary, change the computer configuration in the "Enter configuration" menu. – Enter the VIN into the computer with diagnostic tool command VP001 "VIN Entry".

– Enter the oil wear meter code from the old AT computer (found in the "Identification" menu) by running command VP015 "Transfer oil wear meter".

– Enter the gearbox oil change date with command VP016 "Enter gearbox oil change date". – Switch off the ignition.

– Carry out a check using the diagnostic tool.

– Enter the After-Sales operation date with diagnostic tool command VP008 "Enter last After-Sales

operation date".

IT IS ESSENTIAL TO CONTACT YOUR TECHLINE BEFORE REPLACING AN AUTOMATIC TRANSMISSION COMPUTER.

(17)

● VP001 "VIN ENTRY":

As it is necessary to enter the VIN each time dialogue is established with the diagnostic tool, it must be programmed into each vehicle computer whenever a computer is replaced.

Programming procedure:

– Connect the diagnostic tool

– Refer to automatic transmission fault finding – Select parameter setting VP001 "VIN Entry" – Enter the vehicle's VIN

– Clear the computer memory – Exit diagnostic mode – Switch off the ignition

– Wait for the end of the "power latch" – Double-check the setting

If the stall speed value is incorrect, replace the torque converter, converter lock-up solenoid valve, and oil. If the oil is burnt, also replace the hydraulic control valve and all the solenoid valves.

When replacing the torque converter, ensure that the reaction shaft is securely attached to the hub of the oil pump (swaged shaft).

Note: a stall speed which is too low may be linked to a lack of engine power.

Carry out a road test, observing the engine speed on the instrument panel and the information displayed on the diagnostic tool.

If the engine speed does not vary with each change of gears, replace the hydraulic control valve and all the solenoid valves.

(113)

ALP 4

Automatic transmission malfunction when changing gears

Automatic transmission gear change malfunction may be observed without any fault being stored in the computer.

These malfunctions may be due to contact resistance faults on the selection and progressive engagement solenoid valve (EVS1 to EVS6) control lines preventing the self-test system from detecting a solenoid valve fault or preventing the solenoid valves from being controlled.

(114)

ALP 5

Erratic gear changes

Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault. Electrical measurements of the voltage, resistance and insulation are generally correct, especially if the fault is not present when analysing (stored fault).

Look for damage under the bonnet and in the passenger compartment. Carefully check the fuses, insulators and wiring harness routing. Look for signs of oxidation.

Tactile inspection

While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from "stored" or "present".

You will always be asked for this log:

– when requesting technical assistance from the Techline,

– for approval requests when replacing parts for which approval is obligatory,

– to be enclosed when returning monitored parts on request. The log is needed for warranty reimbursement, and enables better analysis of the parts removed.

IMPORTANT!

NOTE

Any fault on a complex system requires thorough fault finding with the appropriate tools. The FAULT FINDING LOG, which should be completed during the procedure, enables you to keep track of the procedure which is carried out. It is an essential document when consulting the manufacturer.

IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS CARRIED OUT.

The automatic transmission on this model is a DP0, which is also found on other Renault vehicles including the Clio II, Kangoo or Megane.

The automatic transmission computer controls gear-shifting based on several parameters, among them engine torque and the type of driving being done.

All signals travel to the computer by wire, except for those from the injection computer, which use the multiplex network.

Fault finding on the computer is carried out via the multiplex network (CAN).

If Techline approves the computer replacement, proceed as follows:

– Note the gearbox oil condition meter code in the Identification menu: ID018 "Oil condition meter" and the date of the last gearbox oil service ID017 "Gearbox oil service date".

– Switch off the ignition. – Replace the computer.

– If necessary, change the computer configuration in the "Write configuration" menu. – Enter the VIN into the computer with diagnostic tool command VP001 "Write VIN".

– Enter the oil condition meter code from the old automatic transmission computer (found in the Identification menu) using command VP015 "Transfer oil condition meter".

– Enter the gearbox oil change date with command VP016 "Write gearbox oil service date".

– Enter the After-Sales service date with diagnostic tool command VP009 "Write last After-Sales service

date".

– Carry out a check with the diagnostic tool, on the identification screen.

IT IS ESSENTIAL TO CONTACT YOUR TECHLINE BEFORE REPLACING AN AUTOMATIC TRANSMISSION COMPUTER.

● VP001 "VIN entry":

As it is necessary to enter the VIN each time dialogue is established with the diagnostic tool, it must be programmed into each vehicle computer whenever a computer is replaced.

Programming procedure:

– Connect the diagnostic tool.

– Consult the fault finding procedure for the automatic transmission. – Select configuration VP001 "VIN entry".

– Enter the VIN.

– Exit fault finding mode. – Switch off the ignition.

– Wait for the end of Power-latch: over 10 seconds.

● VP009 "Enter last After-Sales operation date":

Every time work is carried out on the automatic transmission in the workshop, enter the date of the operation.
